INVENTOR. PAUL H. TRAVIS ATTORNE Patented May 14, 1 940 UNITED STATES PATENT OFFICE DOOR CHECK Paul'H. Travis, Detroit, Mich. Application December 6, 1939, Serial No. 307,015

4 Claims.

This invention relates generally to door checks of the concealed type for limiting the opening movement of doors and constitutes a continuation-in-part of my application filed May 15, 1939, bearing Serial No. 273,685.

One of the essential objects of the invention is to provide 'a door check that comprises fewer parts and is less expensive to manufacture, assemble and install than door checks with which I am now familiar.

Another object is to provide a door check wherein the arm thereof is provided at one end with sufficient metal about the opening for the attaching pin or pivot to prevent the latter from tearing or pulling through the metal while the door check is in use, and that is provided at its other end adjacent the head of the arm with suflicient metal to take up play in the yieldable cushioning element and metal washer or backer therefor to prevent the latter from rattling while the door check is in use.

Another object is to provide a door check wherein the two arm portions just mentioned are so proportioned one to the other that the yieldable cushioning element and washer may be sleeved over the pivot end of the arm to the head of the arm and will fit tightly upon the arm adjacent the head.

Another object is to provide a door check wherein the arm is a metal stamping and may be accurately and quickly made to meet the requirements.

Another object is to provide a door check wherein the yieldable cushioning element and metal washer may be readily removed and replaced whenever desired.

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Figure 1 is a fragmentary horizontalsectional view through a swinging door, supporting hinge pillar therefor, and door check embodying my invention, and showing the arrangement of parts when the door is in closed position;

Figure 2 is a view similar to Figure 1, but showing the door in open position;

Figure 3 is an end view of the door check shown in Figures 1 and 2;

Figure 4 is a detail view of the washer illustrated in Figure 3;

Figure 5 is a detail view of the yieldable cushioning element illustrated in Figure 3;

Figure 6 is a cross sectional view-through the enlargement beside the head of the arm of the door check; 7 t

Figure 7 is a. cross sectional view through the enlargement at the attaching or pivot end of the door check arm;

Figure 8 is an edge elevation of the arm shown in Figures 1 and 2;

Figure 9 is a view similar to Figure 1, but showing a slight-modification;

Figure 10 is a view similar to Figure 2, but showing the modified form of door check illustrated in Figure 9;

Figure 11 is a detail view of the yieldable cushioning element illustrated in Figure 9;

Figure 12 is a detail view of the washer illustrated in Figure 9;

Figure 13 is an edge elevation of the arm illustrated in Figure 9;

Figure 14 is a cross sectional view taken substantially on the line l4--l4 of Figure 13.

Referring now to the drawings, A is the, arm, B is the cushioning element, and C is the washer of a door check embodying my invention. As shown, the arm A is a substantially flat metal stamping provided at one end with an opening l0 for a pivot pin II and provided at its other end with a semi-circular or segmental head l2.

The cushioning element B comprises a cylindrical body and is preferably formed of rubber or rubber composition. The washer C is preferably a metal disk and constitutes a backer for the cushioning element B.

To accomplish the objects mentioned the arm A is provided beside the head 12 with a substantially rectangular enlargement or shoulder I3 and is provided about the opening III with a rounded enlargement l4. Preferably the cross sectional dimensions on line X of the enlargement l3 are the same as the cross sectional dimensions on line Y of the enlargement l4. Thus, the cushioning element B and washer C may slip over the rounded enlargement it onto the rectangular enlargement l3. The slots l5 and I6 respectively in the cushioning element B and washer C correspond in shape and size to the enlargement l3 so that the edges of such slots fit tightly against and frictionally engage said enlargement. In fact, the construction and arrangement is such that the frictional engagement alone between the enlargement l3 and the cushioning element B and washer C is sufficient to hold such parts in assembled position beside the head l2. As a result, no other securing or fastening elements are required. Moreover, it is unnecessary to crimp or otherwise distort any of such parts to maintain them together, and rattling is obviated entirely. Furthermore, due to the cross sectional dimensions of the rounded enlargement l4 there is sufllcient metal about the opening ID to prevent the pivot pin ll tearing or pulling through the metal at this point while the door check is in use.

In the present instance I have illustrated my door check in combination with a door E and hinge pillar F of a motor vehicle, however it is to be understood that such door check may be used with any form of swinging door and its supporting hinge pillar. As shown, the door check extends substantially horizontally between the door E and its hinge pillar F. The pivot pin II is carried by-two spaced angle plates 20 fixed to the door E. The hinge pillar F is hollow and is provided in a wall 22 thereof with a suitable slot 23 for the arm A of the door check. The

head I 2, cushioning element B and washer C are located within the hollow pillar so that the cushioning element B is engageable with the wall 22 to limit the outward swinging movement of the door when the latter is opened; However, it is apparent that the arrangement just mentioned may be reversed, i. e., the pivot pin H and attaching plates 20 may be secured to the hinge pillar F, and the door E may be apertured to receive the arm A. In either instance the door E would be yieldably checked when opened.

In Figures 9 to 14, inclusive, I have illustrated a slight modification wherein the enlargement I 3 is omitted and the cross sectional dimensions of the arm A are uniform from the rounded end 30 to the head 3|. In this construction the slots 32 and 33 respectively in the cushioning element B and washer C conform in shape and size to the cross sectional dimensions of thearm A and thus flt tightly on the arm beside the head 3|.

Thus, from the foregoing, it will be apparent that the door checks shown and described herein are simple yet strong and durable in construction and can be manufactured at a comparatively low cost. In each instance the cushioning element is preferably made of rubber or rubber composition, however it is apparent that such element may be made of any suitable material for yieldably cushioning the outward movement of the door. Likewise, the washers may be formed of any suitable material to serve efiiciently as a hacker for the cushioning elements. The arms are preferably metal stampings, however they too may be any other material having suflicient strength to function properly in the capacity for which they are designed. The essence of the invention resides in the simplicity of construction whereby the cushioning elements and washers of the respective door check constructions may be held in place solely by frictional engagement with the arms so that it is unnecessary to provide additional fasteners or to crimp or otherwise distort the parts to maintain them in assembled relation. Due to my construction it is also apparent that the cushioning elements and washers may be readily removed from the respective arms and replaced whenever desired.

What I claim as my invention is:

1. A door check having an elongated arm, a

yieldable cushioning element, and a backer for said element, said arm being provided at one end with an opening for a pivot pin and provided at its other end with a head, said arm also being provided beside said head with a wider portion providing a. shoulder, the cushioning element and backer having registering openings receiving said shoulder, the size and shape of said registering openings being substantially the same as the size and shape of the shoulder whereby the edges of the registering openings frictionally engage said shoulder.

2. A door check having an elongated arm, a yieldable cushioning element. and a backerfor said element, said arm being provided at one end with an opening for a pivot pin and provided at its other end with a head, the portion of said arm containing said opening being wider than the arm proper and providing an enlargement, the portion of said arm beside the head being wider than the arm proper and providing another enlargement, the cushioning element and backer having registering openings receiving the second mentioned enlargement, the size and shape of said registering openings being substantially the same as the size and shape of the second mentioned enlargement whereby the edges of the registering openings frictionally engage said enlargement, the width of the first mentioned enlargement not exceeding the width of the second mentioned enlargement so that the cushioning element and backer may be slipped over the first mentioned enlargement to and from the second mentioned enlargement.

3. In a door check, an elongated arm provided at one end with an opening for a pivot pin and provided at its other end with a head, the portion of said arm beside said head being wider than the arm proper and providing a shoulder, the portion of said arm containing said opening being wider than the arm proper and providing an enlargement, the cross sectional area of the enlargement being substantially the same as the cross sectional area of the shoulder whereby a yieldable cushioning element and a hacker therefor may be slipped over the enlargement to and from the shoulder.

4. A door check having an arm, a yieldable cushioning element, and a washer constituting a backer for said element, the arm being provided at one end with an opening for a pivot pin and provided at its other end with a head, the portion of the arm beside said head being adapted to carry the cushioning element and washer, said cushioning element and washer being arranged side by side on said carrying portion and having registering openings substantially conforming in size and shape to the cross sectional dimension of said carrying portion, the portion of said arm containing the opening not exceeding in cross sectional dimensions the cross sectional area of the carrying portion aforesaid beside said head so that the cushioning element and washer may be slipped over the last mentioned portion of the arm to and from frictional engagement with the carrying portion of said arm.
